Black's Law Dictionary
This period was fixed for many purposes in law. Thus, in the case of an estray, if the owner did not claim it within that lime, it became the property of the lord. So the owners of wreck must clnim it within a year and a day. Death must follow upon wounding within a year and a day if the wounding is to be indicted as murder. Also, a year and a day were given for prosecuting or avoiding certain legal acts; e. g., for bringing actions after entry, for making claim for avoiding a fine, etc.
